The beneficial effects of the invention are as follows: The impact type mining machine reciprocating telescopic water supply device has the following advantages:

1. The waterway is arranged on the impact head or on the impact head and the impact guide rod. The telescopic water supply mechanism is arranged inside or outside the power box, the nozzle is arranged on the impact head and connected with the waterway, and the connecting rod is arranged in the connection sleeve. The water outlet end of the pipeline is connected with the connecting sleeve or the connecting rod, the water inlet end of the pipeline is connected with the water source, the waterway is connected with the water outlet end of the connecting sleeve or connected to the water outlet end of the connecting rod, and the connecting rod or the connecting sleeve reciprocates under the driving of the reciprocating member. The telescopic water supply is realized, and the reciprocating impact head of the reciprocating impact type shearer is required to be sprayed internally to reduce the dust, lower the temperature of the impact head, reduce the actual need of the impact head wear, and avoid the impact head reciprocating impact water supply pipeline following the reciprocating impact Damage to the water supply line when the head is telescopic.

2. The impact guiding rod cavity is connected with the waterway. The water source in the pipeline enters the impact guiding rod cavity and the impact head waterway to reach the nozzle through the connecting sleeve and the connecting rod, and fully utilizes the favorable conditions for the impact guiding rod to connect with the impact head and reciprocate. The water supply required for the impact head is sent to the impact head, which reduces the components connected to the impact head required for the spray system in the impact head, reduces the wearing parts outside the box, and allows the connecting piece and the connecting sleeve to be placed in the box. In the body, it is protected from the collision of materials. The structure is simple and ingenious. The impact guide rod is made into a thick water pipeline. The water has a good cooling and cooling effect on the impact guide rod, which improves the service life of the impact guide rod. The rod or the connecting sleeve is connected with the impact guiding rod and has a small installation size and reciprocates with the impact guiding rod. The required installation space is small, the structure is compact, and the installation position is flexible and adjustable.

3. A seal is provided between the connecting rod and the connecting sleeve to prevent water from leaking from the gap between the connecting rod and the connecting sleeve. 4. The relief valve is installed to ensure the stability of the water pressure. The filter is installed at the inlet water source to reduce the pollution damage of the pipeline to the pipeline, connecting parts, connecting sleeves, nozzles, etc.

5. Set the pressure gauge to ensure the stability of the water pressure. The supercharger is set to avoid the failure of the water to reach the nozzle due to insufficient water pressure.

6. The nozzle is arranged on the impact tooth to play a good cooling effect on the impact tooth, which improves the service life of the impact tooth. The nozzle is arranged on the tooth frame, the tooth frame does not rotate outward to convey material, and the solid nozzle and the drum type mining machine The nozzle is less susceptible to being blocked and damaged.

7. The angle of the nozzle head can be adjusted to improve the efficiency of the nozzle, and the nozzle is prevented from doing useless work.

8. Set the atomizer to improve the dust reduction efficiency of the water source, purify the working environment, and set the nozzle shield to protect the nozzle from impact and other damage. Since the rack does not rotate outward to convey material, the nozzle guard can be set larger. Larger nozzle guards do not interfere with discharge.

9. The carrier is provided with a nozzle holder mounting recess, and the dimple effectively protects the nozzle holder from impact damage.

10. The nozzle head and the nozzle seat are installed with seals to reduce the water loss and improve the spray effect.

11. The water tank is opened from the box body and the impact head. The use of the box body and the impact head for the pipeline not only reduces the vulnerability of the peripheral piping, but also improves the utilization rate of the box body and the impact head.

12. There is a quick interface between the connecting rod or the connecting sleeve and the impact guiding rod. The quick interface is provided with a sealing member, which is convenient for use on the site for removal and replacement, and does not affect the production progress.

13. The connecting rod or the connection part of the connecting sleeve and the box body is provided with an anti-damage adjusting member, and the anti-damage adjusting member avoids the impact of the impact head reciprocating impact lateral force on the connecting member and the connecting sleeve.

14. The connecting rod is arranged in the box body, and there is splashing oil mist in the box body, and the splashing oil mist has lubrication protection effect on the connecting rod.

15. The internal and external spraying mechanism does not pass through the power shaft, which avoids the corrosion of the power components and transmission components caused by water leakage. Compared with the spray-type spray system of the drum-type mining machine, the structure is simple, firm and reliable, and has a long service life.

16. The whole water spray system needs to be sealed with less leakage prevention points and less difficulty in sealing, which greatly reduces the manufacturing difficulty. Multiple seals can be set between the connecting rod and the connecting sleeve, and the sealing parts are small, and the sealing is greatly improved from the structural design. The effect of the drum type mining machine is that the rotary sealing point is large, the rotary sealing is difficult, the rotary sealing member is complicated, the rotary sealing strength is large, so the rotary cutting resistance is increased, the connecting rod and the connecting sleeve are sealed easily, the sealing point is small, and the sealing member is simple The sealing is difficult, the resistance of the seal is small, and the power consumption is reduced.

17. Compared with the drum type mining machine cutting section, the waterway system structure is extremely simple, when there are problems such as water leakage and waterway blockage. When the drum type mining machine is repaired, it is necessary to disassemble large parts such as cutting drums and rotating discs for maintenance. The maintenance is complicated and difficult, and it takes time and labor. The reciprocating water supply system does not need to disassemble the cutting parts during maintenance. The commonly used maintenance window can be completed or directly repaired outside the impact power box. The impact type mining machine reciprocating telescopic water supply device has fewer structural components, good technicality of each component, strong versatility between parts, easy maintenance and easy replacement. Safe and reliable, long service life. DRAWINGS
